Default Battery Saver?

Anyone use a battery saver that uses a 9 volt battery and plugs into cigarette port--does it keep all juice to all computers until battery is changed.? No codes appear after new battery install? thx

I never had a problem losing setting, other than perhaps the radio, when installing a new battery.

I used one on my truck and saved all the radio settings. Daily truck doesn't have modern day computer but I ASSUME it will save all settings.
